NOW, THEREFORE, BE IT RESOLVED by the Port Commission of the Port

of Seattle as follows:

M9111.  The Part 150 Study prepared updated Noise Exposure Maps for
Seattle-Tacoma International Airport for Existing (2013) and Future (2018)
conditions. Port staff is directed to submit the updated Noise Exposure Maps to the
FAA for nal review and acceptance.

Section}.   The Part 150 Study is hereby amended to include Continuing
Measures from previous Part 150 Studies and new Abatement, Mitigation and
Program Management Alternatives set forth herein. Port staff is directed to submit
these Alternatives to the FAA for nal review and approval and, upon FAA
approval, to implement the directives in this Resolution, subject to Port and FAA
funding and all other required Port Commission approvals.

W- Continuing Measures:

3) Insulation of Schools:  As required Port, Federal Aviation Administration
(FAA), and State funding permits, continue the sound insulation program
for Highline Community College buildings and schools in the Highline
School District that were previously identied as eligible.

b) Proper_ty Advisory Service: Provide residents and property owners within
the nearby communities access to timely and factual information
concerning noise programs and options for mitigation.

Local Government Remedy Support: Encourage the local jurisdictions to
undertake projects, provide services, and adopt laws that reinforce
neighborhoods and make them more compatible with airport operations.

d) Funding for Land Use and Noise Compatibly Planning: Assist local public
agencies having planning authority within the 65 DNL Noise Contour with
application for reimbursable funding for specic off-airport land use and
noise compatibility planning efforts that are consistent with the Part 150
guidelines and the Port's noise compatibility goals.

Prepare Cooperative Development Agreements:  Continue to address
development potential within local jurisdictions for areas included within
the modied Noise Remedy Boundary.

Explore Limited Rescheduling ofNighttime Flights: This measure involves
the voluntary rescheduling of aircraft ight times for nighttime short-haul
ights.

g) Use VOR Radials to Curb Aircra Driing from Noise Abatement Tracks:
This measure uses very high frequency (VHF) Omnidirectional range
radials (VCR) to curb departing aircraft from driing off the runway
heading tracks as specied in the FAA Tower Order.

h) Preferential Runway Use: This measure implements a preferential runway
system during the nighttime hours for operations through the north ow
nighttime noise abatement corridor.

i)   Use of Flight Management System (FMS) Procedures:  This measure is
designed to encourage the use of FMS procedures to improve noise
abatement corridor compliance.

j)  Use of Ground Eguipment:  This measure recommends the installation of
power and conditioned air in existing and newly constructed gates to
minimize the use of aircraft auxiliary power units.

$991M.  Abatement Alternatives:

3) GroundRun-up Enclosure (GRE):  GREs can provide signicant noise
reduction during aircraft engine maintenance testing. The Part 150's GRE
Siting Study identied three feasible locations that would provide a
quantiable noise reduction impact for the surrounding communities during
engine testing. The Port shall determine an exact location for a GRE on the
aireld through the ongoing Sustainable Airport Master Planning process.

b) Maintenance Run-Up Regulations:  Continue with existing measures and
modify these measures to include the use of the Ground Run-Up Enclosure
(GRE) if constructed.

Expand the Fly Quiet Program: The Port established a Fly Quiet Program
following the recommendation from the 2000 Part 150 Study Update. This
measure would modify the program to include:

a.  Use of Air Trafc Control Tower reporting of operational modes for
comparison to runway use goals
b.  Provisions for the use of a GRE once it's constructed
c.  Different categories of airline operations

52911915.   Mitigation Alternatives:

8")  Noise Contours:  The Port shall adopt the 2018 65 DNL noise contour as
the basis for the Port Noise Compatibility Program and all related programs.

b) Single Famin Sound Insulation: The Port shall provide for the installation
of sound insulation in single-family residential units within the modied
Noise Remedy Boundary based on the 2018 65 DNL Contour.

Owner-Occupied Multi-family (Condominiums) Insulation: The Port shall
provide for the installation of sound insulation in owner-occupied multi-
family units within the modied Noise Remedy Boundary based on the
2018 65 DNL Contour.

d) Tenant-Occupied Multi-family (Apartments) Insulation:  The Port shall
conduct a pilot program to sound insulate tenant-occupied units within the
modied Noise Remedy Boundary based on the 2018 65 DNL Contour.

Avigation Easements for Owners of Mobile Homes on Private Lots: The
Port shall develop a program to offer compensation to owners of mobile
homes on individual lots in return for removing the mobile homes and/or
providing avigation easements for air rights. This would be offered as a
pilot program to eligible property owners within the modied Noise
Remedy Boundary based on the 2018 65 DNL Contour.

0 Churches and Places of Worship Sound Insulation: The Port shall initiate a
formal study to evaluate the noise levels at various churches/places of

-4-

worship within the modied Noise Remedy Boundary based on the 2018
65 DNL Contour.

g) Property Advisory Service: The Port shall provide residents and property
owners within the nearby communities access to timely and factual
information concerning (1) eligibility for noise mitigation programs; (2)
assistance with making decisions on different options; (3) information
regarding the mitigation programs; and (4) assurances that the programs
are intended to improve the living, working, and leisure-time environment.

h) Local Government Remedy Support:  The Port will encourage local
jurisdictions to undertake projects, provide services, and adopt laws that
reinforce neighborhoods and make them compatible with the airport
operations.

i)   Funding for Land Use and Noise Compatibility Planning:  Port staff shall
assist public agencies having planning authority within the 65 DNL Noise
Contour with application for reimbursable funding for specic off-airport
land use/noise compatibility planning efforts that are consistent with the
Title 14 CFR Part 150 guidelines and the Port's noise compatibility goals.

j)  Approach Transition Zone Acquisition:  Port Staff shall acquire on a
voluntary basis residential properties experiencing noise levels of 65 DNL
or greater, located within the South Approach Transition Zone.

k) Prepare Cooperative Development Agreements: Port staff shall continue to
address development potential with local jurisdictions for areas included
within the modied Noise Remedy Boundary.

W. Program Management Alternatives:

a) Evaluate Noise Monitoring and Flight Tracking System:  The Port shall
evaluate the permanent noise monitoring and ight tracking system
software and hardware to determine alternatives for newer, more reliable
and cost effective systems.

b) Periodically Review and, if Necessary, Update the Noise Exposure Maps
gNEMs) and the Noise Compatibilig Program (NCP):  Port staff shall
periodically review the NEMs and NCP to determine if any signicant
changes have occurred to the noise environment in accordance with the
FAA's guidelines.

0) Continue to operate the Noise Ofce: The Port shall adequately staff and
operate the Noise Ofce to carry out provisions of the Part 150 Study and
provide noise-related community programs.
